Frequently Asked
The standard categorizes urinals by pattern—flat back or angle back—with options for flushing rims or rimless designs, across two main sizes. Heights range from 345 mm to 590 mm, with projections and widths varying accordingly; squatting plates are provided in two standard sizes as well. Rimless models are preferred for hygiene, and fixing can be side-mounted or top and bottom mounted. Detailed dimensions ensure compatibility and ease of cleaning as per the standard.
The cleanability test involves applying a 0.1% organic dye solution on the interior flushing surfaces of urinals mounted in their normal positions. For bowl urinals, a 2.5-litre flush is applied via an automatic cistern with a 12.5 mm bore spreader mounted at least 90 cm above. For squatting plates, the dye is applied below flush holes, followed by pouring 2.5 litres of water along these holes. The test passes only if no dye residue remains post-flushing, ensuring hygienic surfaces.
Waste outlet holes for bowl pattern urinals without flushing rims must conform to specific dimensions: internal diameter of 45 ± 2 mm, outlet flange approximately 65 ± 5 mm, and depth not less than 20 mm. The distance from the back to the center of the outlet varies by urinal pattern, typically 100 mm for flat back and 150–225 mm for angle back models. Fixing holes of minimum 6.5 mm diameter are also specified to ensure secure installation and compatibility.
Manufacturers are required to mark urinals and partition plates clearly and indelibly with their name or trademark and the batch or lot number. Additionally, use of the BIS Standard Mark is optional but regulated under the Bureau of Indian Standards Act, 1986. To use this mark, manufacturers must obtain a license from BIS, which includes ongoing surveillance and product conformity checks to uphold quality standards.
Yes, the standard specifies fixing methods for squatting plate urinals that include an integral longitudinal flushing pipe connected through three 13 mm diameter holes to the sump, ensuring that the installation height is maintained. Partition plates should be installed securely as illustrated in the relevant figures, guaranteeing stability and correct spacing. Deviations in patterns and sizes may be permitted with agreement, provided functional dimensions and other requirements are met.
